Here, carrying out the extraneous air of heat exchange with condenser 115, flowing into side end face 124 by air enters condenser
In 115, heat exchange is carried out via fin 121 and pipe 123, the interval 122 between fin 121 is flowed and passes through condenser
115。
Now, if dust, the dust of particularly cotton like in air flow into side end face 124 by the air of fin 121 and hung
Firmly start to accumulate, then occur to block at interval 122 and cause the reduction of heat-exchange capacity.
But in the condenser 115 of present embodiment, the dust that side end face 124 is flowed into by being arranged at air adheres to
Mitigation portion 125, the accumulation of dust becomes difficult, so can suppress the reduction of heat-exchange capacity.
That is, form condenser 115 air flow into side end face 124 dust attachment mitigation portion 125 to the He of upper surface 126
To lower surface 127, the angle of the inflow air of the solid arrow expression by Figure 16 is diminished, dust is difficult to adhere to.
It is described in detail, dust attachment mitigation portion 125 tilts to upper surface 126 relative to leaked-in air stream.By
This, the more than half dust encountered to upper surface 126 being mixed into the dust in air, along under the inclination flow direction to upper surface 126
Trip side starts concentration and is deposited in valley.Grown to the size of upper surface 126, so dust is integrally formed the state compared with unfertile land accumulation,
The rising of air drag can be suppressed.In addition, to lower surface 127, (included approximate horizontal for horizontality to lower surface 127
State), turn into the end face with air stream identical direction.Therefore, the accumulation of dust is nearly free from itself, also, even if dirt
Angstrom accumulation, also fallen because of gravity and air stream.
Moreover, even across it is longer during use, dust be gradually deposited in a side to upper surface 126 and in fin
Start to produce blocking between 121, in the accumulation for being also nearly free from dust to lower surface 127 of the opposing party, so to lower surface 127
In fin 121 between turn into air by-pass road 121a, air flows as the dotted line arrows.
That is, in the case of as the overall viewing of condenser 115, it can reduce what is blocked caused by dust for a long time
Influence, heat-exchange capacity reduction can be suppressed.Therefore, energy-conservation can correspondingly be improved with heat-exchange capacity reduction can be suppressed
Property.
Also, in the condenser 115, from dust attachment mitigation portion 125 to upper surface 126 and to the structure of lower surface 127
Into chevron shape portion 128 apex portion fin surface by being formed relative to the inclined inclined plane 129 of air stream, so dirt
Angstrom the blocking for being piled into One-step delay, can suppressing to upper surface 126.
That is, the chevron shape intersected to upper surface 126 and to lower surface 127 in dust attachment mitigation portion 125 is attached to
The dust in portion 128, do not hung together with the air stream shown in arrow b, c, d such as Figure 18 by the summit ora terminalis of chevron shape portion 128
The fin surface between the fin 121 along inclined plane 129 downstream flow out by side as former state for residence.Because as shown in figure 18,
The fin surface of chevron shape portion 128 tilts relative to the flowing of air.
Moreover, fin front elevational sectional tilts also relative to the direction of air stream, so the apex with chevron shape portion 128
The air of the ora terminalis direct collision divided turns into a part as shown in Figure 18 arrows a, so can reduce by chevron shape portion 128
The dust that apex tangles itself.Thereby, it is possible to the summit ora terminalis reduced by chevron shape portion 128 to tangle edge to upper surface 126
Flow further downstream is deposited in the amount of the dust itself of valley.
Therefore, it is possible to effectively suppress because dust is deposited in upper surface 126 and caused by air drag rising, accordingly
It ground, can further suppress the reduction of heat-exchange capacity, improve energy saving and durability.
In addition, in chevron shape portion 128, downstream is made more to intersect to inclined plane 129 compared with inclined plane 129
Direction tilt, so in the fin surface of chevron shape portion 128, as shown in Figure 18 arrow e, in the inclined plane of apex portion
129 and its downstream part downstream lateral incline 130 between turbulization.The peeling of air-flow is produced because of the turbulent flow,
The accumulation of dust can be suppressed.
Therefore, it is possible to make to be inclined by being tangled to upper surface 126 for face 129 and the part of downstream lateral incline 130 downstream
The dust of accumulation is peeled off and reduced together with air-flow.Hindered as a result, can further suppress the air caused by dust blocks
The rising of power, it is possible to increase energy saving.
Also, fin 121 is zigzag shape in the flow direction whole region of air, so being produced on the surface of fin universe
The peeling of anger stream, dust is difficult to accumulation and is attached to fin surface in the flow direction whole region of air.
Therefore, it is possible to more efficiently suppress heat-exchange capacity reduction, energy saving can be further improved.
In addition it is also possible to the pipe 123 of the part for most leaning on air inflow side as fin 121 being arranged at and chevron shape
Position corresponding to portion 128, without being arranged at valley.Thereby, it is possible to further suppress the reduction of heat-exchange capacity.
That is, by said structure, valley is difficult to the resistance for bearing the air stream caused by pipe 123, so being blocked in dust
Start it is initial when, the flow velocity of air accelerates.Moreover, the dust that be deposited in valley comes off because of the fast air of the flow velocity.Its
As a result, it is possible to postpone the dust accumulation to valley.
Therefore, it is possible to further suppress the reduction of heat-exchange capacity, it is possible to increase energy saving and durability.
In addition, the freezer shown in present embodiment, will can be flowed to for being taken into condenser 115 extraneous air it is narrow
Seam opening 119 is arranged to relative with the apex portion of the chevron shape portion 128 of condenser 115.Thus, flowed from slit opening 119
The air entered, the chevron shape portion 128 that mitigation portion 125 is adhered to the dust of condenser 115 are gone, and are flowed into from its front.
